This business idea is definitely not for the faint of heart, and is a little extreme for me, but nonetheless it's been done as a side hustle for many people. You can start by holding a placard or wearing a sandwich board. If you think this is a good side business idea, you can go all the way and turn it into a full on small business idea with enough hard work—plus you won't have to deal with all the issues other more complex businesses have to constantly think about (like reducing churn).
